Police took the husband of a murdered New Jersey radio host into custody Tuesday morning, five years after she was found dead in her Linwood home.

Dr. James Kauffman surrendered to authorities at his Egg Harbor Township office following a tense 45-minute standoff that began with him showing cops a 9 mm handgun, the Atlantic County prosecutor’s office said.

“We were able to talk him off the ledge,” Damon Tyner, Atlantic County Prosecutor told ABC. Adding that Kauffman was taken to a psychiatric program where he is being monitored.

Kauffman will be charged with unlawful possession of a weapon among other weapons charges, though Tyner said no charges related to April Kauffman’s slaying would be immediately brought.

Prosecutors said warrants to search Kauffman’s home and office were issued as investigators look into “leads pertaining to criminal activity.”

April Kauffman was found dead of gunshot wounds on May 10, 2012 inside her bedroom. No one has ever been charged in her death.
